NodeMCU Choreography Automation by CoAP

The internet of things (IoT) plays an important role in our lives and this role is significantly increasing. The combination operation of a device or a NodeMCU is used to reduce cost, gather information, and command and control devices. The most beneficial use of the IoT is to help smart farms, home automation, smart factories, smart cities and big data. The aim and contribution of this research are to reduce costs and increase the effectiveness of the use of the IoT. This study uses NodeMCU to make a composition model-driven automation using a choreography architecture. The Contained Application Protocol (CoAP) is used to the reduce costs of the interface between the compositions. The advantage of using the CoAP composition is that it can be made in the limited condition of the devices. For the precision and accuracy of the composition, we carry out experiments with 5 to 20 compositions.
